RAILWAY BRAKE BEAM.

- Application filed l'iay 12,

of the strut to receive a. sliding chair for a third point suspension or a link suspension.

I have illustrated my invention: herein as applied to a reversible strut of. the character specifically described in my pending application for Letters Patent, Serial No. 532,465,, filed January'QS, 1922, which has nowbecome- Patent Number 1,4823% dated October 17, 1922, and also tOrZDIlOIl-lGVBISlble one-piece forged-metal strut, the novel feature of my invention being applicable to" the. forward end of either a reversible strut or a non-reversiblestrut. The strut 1n either'casepresents a solid forward end connecting the two-sidemembers of the strut,-

I andto this; endI apply the novel supporting attachment constitutingmy invention,v this attachment being of forged metal and formed from an integral or one-piece blank and having a rearend' to be secured to the forward end of the strut and two apert-ured side arms affording seats for the tension member or truss rod: and 'means for supporting a sliding chair fora three-point suspension or properly receiving the-lower end of a link suspension.

The present invention pertains there-fore to a special supporting bracket tobe secured to and for use'in combination with the- 'forward end of the strut of a trussed brakebeam, said bracket having two arms. and. thereforebeing of duplex character and said I armszaffording seats for the central portion of the truss-rod and meansfor receiving a sliding chair suspension or the lower end. of

. a link suspension.

The invention will be fully understood from the I detailed description hereinafter presented, reference being hadr to th'e accompanying. drawings 1n which "Fig. 1 is atop view ofa POTtlOn of a a tens-ion member 1922. Serial No. 560,339.

In the dra\vings,-1() designates a channel shaped compression member of a brakebeam, 12 the truss rodg: and 9- a reversible strut having corresponding; SidememberslS and aflati end; member 14 connecting said sides. The strut shown in Fig. 1i -is of' the reversible type d'esc-ribed' in detailin my aforesaid application N0:'532',4t65,-a1id I" do not deem it necessary to describe the' 'features connecting the back end of the strut with the compression member in a unanncr rendering the strut reversible; since there are ma y forms Of reversible: strutsand the I formillustrated in" Figs. .1-' and 2 may be regarded merely as illustrative of one form of reversible strut. The compression member 10 is shown as'of channel' shape; but/1n respect to my ll'lVeIllIlOIl said compression member maybe of any suitable or desirable shape adapted to receive the strut. The tIUSs'rQd 12 is of the usual type and affords a tension member.

Upon the forward end 1450f the strut'9-is swiveled thesupporting bracket 15cc myinvention, this bracket oomprising in one'integral: piece,- two forwardly proj ectin'gr parallel side arms 16 andra back endi'member' 17 connecting said arms and adapted to be secured against the forwardifiat end 14 of the-strut 9. The support or braclmt 15 is formed from azblank of forged 'or'wrought meta]; and is primarily inwt'he' flat as shown and a strut eqnipped with forwardly and having at their lower sides in Figs. 1 and 5. The side arms 16 of the support or bracket 15 correspond with each other and are arched downwardly and forwardly and at their forward ends are formed with transverse openings 18 encircled by bushings 19, serving to strengthen the arms at the openings 18 therein and to afiord broad bearings for a bolt or other means by which a chair, not shown, for a third point suspension, may be applied to said support or bracket.

The blank shown in Figs. 4 and 5 is bent to form the back end 1'7 and forwardly projecting sides 16, and said end 17 is apertured, as at'20, to receive a pin or rivet 21, by means of which the support or bracket 15 is connected with the end 14 of the strut 9, said end 14: being also apertured to receive said pin or rivet 21, as indicated by dotted lines in Figs. 1 and 2. The pin or rivet 21 has a counter-sunk head at the forward face of the end 17 of the support or bracket and may have an exposed head 22 on its opposite end. In the construction shown in Figs. 1 and 2 the pin or rivet 21 is loosely headed at its rear end and forms a swivel around which the strut 9 may be turned to the right or left for positioning the same. In their lower sides back of the openings 18, the side members 16 of the support or bracket 15 are recessed, as at 23, to form seats for the truss-rod or tension member 12, the recesses 23 curving backwardly and then forwardly projecting extensions 24 which extend below a portion of the truss-rod and aid in setting said rod in longitudinal line with the strut. The recesses 23 have forward edges which curve upwardly and back wardly, as shown in Fig. 2, and serve to direct the truss-rod to the back portion of said recesses and above the extensions 24:. The central vertical portion of the blank shown in Figs. 1 and 5 forms the back end 17 of the support or bracket 15 and thence the corresponding side. portions of said.

blank are bent forwardly to create the parallel arms 16 having the recesses 23 and extensions 24, the whole being in one integral forged or wrought metal plate.

In Fig. 8 I illustrate the same support or bracket 15 applied to the flat forward end 25 of a non-reversible strut 26, this strut 26 beingformed from abar of forged metal and the details of which need not be herein described. The support or bracket 15 of Fig. 3 is secured by a rivet 27 to the end 25 of the strut 26, and since the strut 26 is not reversible, the rivet 27 may rigidly secure the support or bracket 15 in fixed relation to the strut 26.

I do not limit my invention to the special construction of the strut, since the same is applicable to any strut having a forward end adapted to receive it. My invention comprehends the particular construction shown of the support or bracket 15 formed of a single stamping of forged metal, in combination with the strut, whether reversible or not, and adapted to receive the tension member 12 and also afford means for receiving the chair, not shown, of a third point suspension or a link suspension, not shown, both forms of suspensions being familiar in this art.

l/Vhat I claim as my invention and desire to secure by Letters-Patent, is:

1. A brake-beam comprising a compression member, a tension member, a strut extending between said members and having a forward flat end portion and parallel sides and a support or bracket for a third point suspension having a back and forwardly projecting parallel arms and secured at said back against the flat forward end of said strut, said support or bracket being in one integral stamping of forged metal and said arms having apertures formed therein, with bushings around the same, to receive the securing means for the suspension member and being recessed in their lower sides back of said apertures to receive and afiord seats for the central portion of the tension memher.

2. A brake-beam comprising a compres- 'sion member, a tension member, a strut extending between said members and havin an apertured forward end portion and parallel sides and a support or bracket for a third point suspension having an aperturedback plate member and forwardly projectingparallel arms and secured at said back to the forward end of said strut, the secur- 7 ing means being a headed pin applied through sa1d apertures in said back member and the forward end of the strut, said sup-' I port or bracket being in one integral stamping of forged metal and said arms having apertures formed therein for the securing means for the suspension member and being recessed upwardly and backwardly in their lower sides to receive and afford seats for I the tension member, said recesses being partly closed below the tension member by extensions projecting forwardly from the lower back portion of the support or bracket and below said tension member.

3. A brake-beam comprising a coinpression member, a tension member, a reversible strut extending between said members and having an apertured forward end portion, a support or bracket for a third point suspension having an apertured back plate member engaging said'forward end of the strut and forwardly projecting parallel side arms, and a pin inserted through'said back and said forward end of the strut and swiveling the support or bracket to the strut, said support or bracket being in one integral stamping of forged metal and said arms having apertures formed therein for the securing means for the suspension member or bracket and below said tension member.
